GI Treatment Planning & Management 2 — Questions and Answers
Question 1: A patient with Crohn's disease has failed mesalamine therapy. What is the most appropriate next step in management?
- Increase mesalamine dose
- Initiate corticosteroid therapy (Correct answer)
- Proceed directly to surgical resection
- Start probiotic supplementation

When 5-ASA agents like mesalamine fail in Crohn's disease, corticosteroids are the standard next step to induce remission.
Question 2: Which antibiotic combination is the first-line treatment for Helicobacter pylori eradication in the US?
- Amoxicillin + metronidazole

- Doxycycline + bismuth
- Ciprofloxacin + metronidazole + PPI
Correct answer: Clarithromycin + amoxicillin + a PPI
Triple therapy with clarithromycin, amoxicillin, and a PPI remains standard first-line H. pylori eradication in low-resistance areas.
Question 3: A cirrhotic patient develops ascites for the first time. What is the initial management strategy?
- Paracentesis immediately
- Sodium restriction and spironolactone (Correct answer)

6-mercaptopurine is considered relatively safe during pregnancy and maintaining disease remission is prioritized to avoid flares.
